Brand "X"

[Dirk Broer]

There are two ways of going broke with GPU computing. One is by buying a card that you can't afford to pay, the other is by buying a card which power needs are such that you can't afford to pay the power-bill.
Just as with people that write about cars, who have the tendency to describe the latest Ferrari's, Lamborghini's and other unobtainable sports cars, I will now describe which nVidia-cards to avoid like the plague, however good performers they are. They will let you go broke both ways!
